This invention pertains to charts designed for giving the distance from station to station along a particular route and an object of the invention is to render clear at a glance the distance between the terminal stations on a given route or between either of said terminalstations and any one'of the t intermediate or way stations. i

Other objects and advantages will appear in the subjoined detail description.

The accompanying drawing illustrates the invention and the fignre is a plan view of the chart.

The route on which the various stations are located may be a railroad route or highway route and in the instance shown in the drawing, the routes are boulevard or highway routes. a

The term station employed herein represents any particular point that it may be desired to designate on the chart. In the instance shown in the drawing two routes are indicated, the coast and inland routes from Los Angeles to San Diego. The chart maybe read, for the coast route, by holdingit in one position and then by reversing the chart end for end inland route.

The names of stations are indicated at a and alined withsaid names of stations are characters 7) in columns representing diiferent distances in any preferred unit ofmeasurement. Each character b in the first column represents the distance between the starting station and the station of which the name appears opposite said character, in the instance shown Los Angeles being the starting station. lEach character b in the second column represents the distance be tween the second station and the station of which the name appears opposite said character, in the instance shown' Pio Pico Old Home being the second station. Each character b in the third column represents the distance between the third station from the starting station and the station of which the name appears opposite said character, in this instance X Road for La Habra and Brea. Likewise the fourth column of Specication of Letters Patent.

it may be read for the DISTANCE-CHART.

characters b is read in conjunction with the name of the fourth station, the lifth with thename of the fifth station, the sixth with the name of the sixth station, and so on.

For convenience in reading the charts it may be desirable to designate the various columns by the names of the stations as indicated at c in alinement with said columns. From the foregoing it is clear that the columns of characters decrease in length from left to right of the chart, the number of distance indicating characters in each column decreasing by one. At the head of each column is a naught, saidv naught designating the starting point for reading the distances.

To make clear the use of the chart, it may .be assumed that the starting station is Los Angeles, as indicated in the drawing, that the nish terminal station is San Diego, that the intermediate stations are as given in the drawing, and that the characters o are the 'distances in miles. By the use of the first column to the right of the stations, it is clear that the distance between Los Angeles and any one of the other stations, reached successively in the trip from Los Angeles to San Diego, is' designated by the appropriate number representing miles. For instance, the distance from Los Angeles to Oceanside is 90 miles as indicated in the chart and the distance from Los Angeles to San Diego is 133 miles.

If we wish to know the distance, foi1 instance, from` Oceanside to San Diego, we trace down the column designated Oceanside, beginning atnaught Opposite Oceanside, and find at thebottom of the column opposite SanDiego the number 43 which is the distance required in miles. In this column designated Oceanside are characters representing vthe kdistances betweenfOceanside and Carlsbad Station, the distance being three miles; from Oceanside to Cardiff 14 miles, and so on.

It will be seen that the number in each successive column reading from left to right opposite each name of a station is the diierence between the number in the next preceding column opposite said name of a station and the number appearing at the head of said next preceding column; for instance, 61 appears in the fourth column opposite Oceanside, and 68 is the number in the third or next preceding column opposite Oceanside The number 7 is at the head separately and those of one set being in` of the third column and subtracting 7 from' 68 leaves 6l, Which is the number of miles from Anaheim to Oceansidel This-is name of a station as the number of miles from the station designating the succeeding column to the neXt preceding station; Thus 45 opposite Oceanside is the distance in miles from Oceanside to Irvine Station, and this distanceis as much less than 54 in the preceding column opposite Oceanside as the indicated mileage from Santa Ana to the next succeeding station, Irvine Station, which is 9 miles.

The stations and distance indicating characters are arranged in separate sets, one set being for each route.-

The characters of each set are arranged in the form of a triangular block and the stations and 'distance indicating characters of one set are inverted with reference to the stations and distance indicating characters of the other set.

I claim:

1. A distance chart having names of stations arranged in al column, and distance indicating characters located opposite said names of stations, in successive columns, the number of distance lindicating characters in each column decreasing by one and t-he value of the last distanceindicating character appearing opposite any given name of a station being as much less than the valueof the character appearing in the same column opposite the neXt succeeding name of a station as is the distance from said first named station to the said succeeding station.

2. A dist-ance chart having names of stations arranged in columns, and distance in dicatingf characters located opposite said names of stations, in successive columns, there being two sets of names of stations and distance indicating characters arranged verted Withreference to those 'of the other set and each set of characters being in the fornrof a triangular block, in each set the number of distance indicating characters in each column decreasing by one and the value of the last distance indicating character appearing opposite any given name of a station being as much less than the value of the character appearing in the same column cpposite the next succeeding name of a station as is the distance from said first named station to the said succeeding station.

3. A distance chart having names of stations arranged in a column, and distance indicatingA characters located opposite said names of stations, in successive columns, the ditferen'ce between the value `of the distance indicating character appearing in any column opposite vany given name of a station and the value of the distance indicating character appearing in the same column opposite the next succeeding name of a station being equal to the value of the last distance indicating character appearing opposite the name of said succeeding station.

i. A distance chart having names of stations arranged ina column, and distance indicating characters located opposite said names of stations, in successive columns, the number of distance indicating characters in each column decreasing byone and the characters in any given column denoting the distance respectively from the station named opposite thehead of said given columnto the succeeding named stations.

55A distance chart having names of stations arranged in a column, and ldistance in- A dicating characters located opposite said Y names of stations, 1n successive columns, the

values of the distance indicating characters opposite any given name oi" a stat-ion being as much less than the values of the distance indicating characters in the same columns respectively appearing opposite to the next succeeding name of a station as the distance fromany given preceding named station to the given station is less'thanthe distance from said given preceding named station to said succeeding named station.
